Design Notes
Decouple all VDD and VDDA pins with 100nF ceramic capacitors placed as close to the pins as possible. Additionally, use a 4.7uF capacitor on VDDA for analog noise filtering. The VREF+ pin should be connected to a clean reference voltage, typically 3.3V, with a 1uF capacitor to ground. Proper decoupling is critical for ADC accuracy and stable operation.
For the LQFP-64 package, ensure a solid ground plane under the device. Route the crystal oscillator (if used) with short traces and keep it away from high-speed digital signals. Place the boot configuration resistors (BOOT0 and BOOT1) with pull-downs to ensure reliable startup. Use a 4-layer PCB for optimal EMC performance.
Do not exceed the absolute maximum ratings: VDD max 3.6V, and any I/O pin voltage must be within VSS-0.3V to VDD+0.3V. Ensure the NRST pin is pulled high with a 100nF capacitor to ground for reliable reset. When using the ADC, avoid floating input pins by configuring them as analog inputs. For CAN communication, terminate the bus with 120 ohm resistors at both ends.
